image - Official Wyn Package

Image utilities for Wyn: format detection, buffer math, and metadata helpers. Pure Wyn, no system dependency. (Decode/encode/resize via C bindings is future work.)

Install

wyn pkg install github.com/wynlang/image

Usage

import image

// Format detection from file extension
print(image.image_format("photo.png"))           // png
print(image.image_format("scan.jpeg"))           // jpg
print(image.image_is_supported("photo.bmp"))     // true
print(image.image_is_supported("doc.pdf"))       // false

// Buffer math: RGBA buffer for an 800x600 image
print(image.image_buffer_size(800, 600, 4))      // 1920000

// Format dimensions for display
print(image.image_dimensions_str(1920, 1080))    // 1920x1080
